Arrhenius Acid Definition: Hydronium breaks up to yield an H+ in solution. Arrhenius Base Definition: Hydroxide is an OH-dissolved in water. Bronsted-Lowry Acid Definition: Hydronium is an H+ donor regardless of solution. Bronsted-Lowry Base Definition: Hydroxide attacks and accepts the H+ from hydronium.Lewis Acid Definition: The H+ on Hydronium accepts the attacking electron pair to form a bond.ronsted-Lowry Acid Definition: Hydronium is an H+ donor regardless of solution.

It is believed that the first Ancient Chinese fire works were made in Han Dynasty (206 BC-220 AD). Fireworks in Ancient China were originally used for shows, christenings and special funeral ceremonies.
True fireworks did not exist until saltpeter was added to the mixture to create black powder, the first chemical explosive, one thousand years later. Black powder was probably first made in China, but some scholars suggest that it may have been invented by the Arabs.
